Oscar Pistorius' family have released the first footage of the Olympian in training since girlfriend Reeva Steenkamp was shot dead on Valentine's Day.
Bearded, Pistorius does not speak in the 30-second online clip. He was "overcome with emotion" as he returned to light training, his agent Peet van Zyl has said.
Speaking to the Associated Press, Van Zyl explained he was contacted about a week ago by Pistorius, who expressed a desire to return to a regular track routine.
Pistorius will go on trial for the murder of Ms Steenkamp next month, but a short package of him in "low key" training has been posted online.
A statement posted on the athlete's website on said he was "not not contemplating a formal return to athletics", but training aided the "mental and emotional equilibrium to process his trauma".
It added: "His focus, at this point, remains entirely on the court case."
